All items on a single page … do you mean all entries?
re: Setting pagination to false only stops me from being able to browse pages.
This is likely due to the PHP maximum script execution setting or the memory allocated to PHP being exhausted. This is not a Connections limitation, same thing would happen if you tried to list n-number of WordPress posts on a single page too. You could try increasing those values to see if that’ll work.
You can visit the view all page which just lists the entry names. Generally you can view quite a few Connections entries before limits are reached because it only shows the names. The link would be:
Hope that helps!
